There's probably some sort of "old sports rivalry" element going on in some cases. It's possible (though I'd prefer not to think so) that the Richard Sherman thing has riled up some areas against Seattle. Both states tend to have net population imports, so it's not like there are a bunch of Washington expats in Michigan, or Colorado emigres in Mississippi.
Anyway — an interesting way of judging popular sentiment.
